Remarks
IDesignerOptionService provides an interface that can be used to retrieve and update the values of the Windows Forms Designer options, which are listed within the dialog displayed by the Options command of the Tools menu of the Visual Studio development environment. The GetOptionValue method retrieves the value of a specified option. The SetOptionValue method sets a specified value for a specified option.
Methods
| GetOptionValue(String, String) |
Gets the value of the specified Windows Forms Designer option. |
| SetOptionValue(String, String, Object) |
Sets the value of the specified Windows Forms Designer option. |
